Given numbers are 393,445,483,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,445,483,680 is 3829281960.
Find LCM of 393,445,483,680 with Prime Factorization
| 3 | 393, 445, 483, 680 |
| 5 | 131, 445, 161, 680 |
| 131, 89, 161, 136 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 131 x 89 x 161 x 136 = 3829281960
Therefore, the lowest common multiple of 393,445,483,680 is 3829281960.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
393 x 445 x 483 x 680 = 57439229400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
393 : 1, 3, 131, 393
445 : 1, 5, 89, 445
483 : 1, 3, 7, 21, 23, 69, 161, 483
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,445,483,680, is 1.
Now, the common factors can be found like this.
393:3x 131
445:5x 89
483:3x 7x 23
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 57439229400/(1x15)
LCM = 57439229400/15
LCM = 3829281960
Thus, we can understand that the LCM of 393,445,483,680 is 3829281960.
